Verdict
The clearest difference is price: ArcEmu at Free against Castle Smasher's $1.99. ArcEmu also leads on update cadence (every 2 weeks vs every 17 months) and ratings volume (1.3K vs 43). Castle Smasher's advantage is in-app purchases (none vs 10) and iOS requirement (8.0 vs 16.0). On rating, ads and device support there is nothing between them.
